About Digital Object Identifiers (DOIs)

DOI DEFINITION

A DOI, or Digital Object Identifier, is a unique string of numbers and letters that permanently identify the location of an article, or other work, on the web. A DOI is a permanent or persistent link. 

PRESENTED as ACTIVE or INACTIVE

When you locate an article, DOIs may or may not be listed as active links.

To make a DOI active, simply add http://dx.doi.org/ before the DOI.  You can also locate the article from an non-active link by pasting the DOI into a DOI resolver.  https://dx.doi.org/

DOIs are NOT UNIVERSAL

Not all articles have a DOI.
